Rotator cuff From Wikipedia, the free encyclopedia. In anatomy, the rotator cuff (sometimes incorrectly called a rotator cup, rotor cuff, or rotary cup) is a group of muscles and their tendons that act to stabilize the shoulder. The four muscles of the rotator cuff are over half of the seven scapulohumeral muscles.

Rotator Cuff Injury Rotator Cuff Injury Overview. The rotator cuff is made up of four muscles that help move and stabilize the shoulder joint. Damage to any or all of the four muscles and the ligaments that attach these muscles to bone can occur because of acute injury, chronic overuse, or gradual aging.ther muscles that help move and stabilize the shoulder include the deltoid, teres major, corachobrachialis, latissimus dorsi, and pectoralis major. When the rotator cuff is damaged, a variety of issues arise: 1  Pain and spasm limit the range of motion of the shoulder.

Rotator Cuff Mechanics The shoulder complex comprises 30 muscles. These muscles both move the shoulder and stabilise it - 'movers' and 'shakers'. The rotator cuff muscles predominantly stabilise the glenohumeral joint, but also contribute significantly to movement. The rotator cuff muscles are: Supraspinatus.

Rotator Cuff Tears Rotator Cuff Tears. Also Known as: Tendon Tear, supraspinatus tendon tear. The rotator cuff is a group of tendons that connects the four muscles of the upper shoulder to the bones ( see Anatomy ). The strength of the cuff allows the muscles to lift and rotate the humerus (the bone of the upper arm). The tendons run under the acromion (part of the shoulder blade) where they are very vulnerable to being damaged. This can lead to a tear resulting in a painful, weak shoulder.

Rotator Cuff Repair The rotator cuff consists of muscles and tendons that hold the shoulder in place. It is 1 of the most important parts of the shoulder. The rotator cuff allows a person to lift his and her arm and reach up. It stabilizes the ball-and-socket joint of the shoulder and allows for normal shoulder mechanics.trains or tears in the rotator cuff. Inflammation of the bursa (bursitis) in the shoulder. Inflammation of the tendons (tendinitis) in the shoulder. Recurrent pain, limited ability to move the arm, and muscle weakness are the most common symptoms.

- The rotator cuff is a set of four muscles that serve to stabilize and rotate the shoulder, attached by strong tendons to the upper head of the humerus. During abduction, the supraspinatous and infraspinaoous muscles abduct and rotate the head of the humerus.

- The rotator cuff is a team of 4 muscles and connecting tendons that attach your upper arm to your shoulder blade. These muscles, supraspenatus (top of the shoulder), subscapalaris (front of the shoulder), and infraspinatus and teres minn (back of the shoulder), comprise the rotator cuff.endonitis, or inflammation of the tendons, is the most common cause of rotator cuff pain and often results from simply overusing your shoulders. You’ll experience moderate to severe pain in the shoulder area and some limited range of motion.

- Muscles: Rotator Cuff. The main muscles that are used in conjunction with the glenohumeral joint are the group of muscles known as the rotator cuff. The rotator cuff is made up of four muscles, the supraspinatus, subscapularis, infraspinatus, and teres minor.All four of these muscles connect the scapula to the humerus.ne main purpose of the rotator cuff muscles is to pull the humerus into the scapula such that the two bones are fitted tightly against one another. Thus rotator cuff muscles are important for stabilizing the glenohumeral joint.

- The rotator cuff is a group of four tendons and muscles that converge around the shoulder joint at the top of the humerus, the upper arm bone above the elbow.Together, they form a ''cuff'' that both holds your arm in place and allows it to move in different directions.hile your shoulder is one of your most mobile joints, it's also somewhat weak. Too much stress -- or too many fastballs -- can cause partial tears and swelling in the tendons of the rotator cuff. Abrupt stress may even cause one of the tendons to pull away from the bone or tear in the middle of the tendon.

Rotator Cuff Disorders - Topic Overview The rotator cuff keeps the upper arm bone in the shoulder socket and lets you raise and twist your arm. The shoulder is a ball-and-socket joint. The ball at the top of the upper arm bone fits into the socket of the shoulder blade. This socket is shallow, which lets you move your arm in a wide range of motion.otator cuff disorders include: 1  Inflammation of the tendons (tendinitis) or of a bursa (bursitis). 2  Impingement, in which a tendon is squeezed and rubs against bone. 3  Calcium buildup in the tendons, which causes a painful condition called calcific tendinitis. 4  Partial or complete tears of the rotator cuff tendons.

Cuff (Rotator) Tear Arthropathy The rotator cuff is a unique structure in the shoulder that is formed by four tendons. These four tendons attach to four muscles that help keep the shoulder stabilized in the socket (or glenoid) and help rotate the upper arm inward and outward.uff tear arthropathy is the result of long standing lack of rotator cuff function. In almost all cases, repair of the rotator cuff tear is no longer an option. Surgery for cuff tear arthropathy is done when pain and decreased motion continue after conservative care.
